QRadar installations

There are two ways to install QRadar® on your hardware: a software installation, or an appliance installation.

Appliance installation

An appliance installation is a QRadar installation that uses the version of Red Hat® Enterprise Linux® (RHEL) included in the QRadar ISO. An appliance installation on your own hardware or in a virtual machine requires you to purchase a software node entitlement. Contact your QRadar sales representative for more information about purchasing a software node entitlement. You do not need to configure partitions or perform other RHEL preparation as part of an appliance installation. Choose this option, if RHEL is not already installed. Proceed to Installing a QRadar appliance. However, if the hardware/virtual instance configuration varies from our listed specifications, the version of RHEL included in the QRadar ISO may not install properly. In that case, you should attempt a software installation.

Software installation

A software installation is a QRadar installation that uses a RHEL operating system that you provide. The RHEL version required for your installment must be provided by a 3rd party. You must configure partitions and perform other RHEL preparations before a QRadar software installation. Aside from RHEL, all software installations requires you to purchase a software node entitlement. Contact your QRadar sales representative for more information about purchasing a software node entitlement. Proceed to QRadar software installations.
